Detailsinfo

A vulnerability, which was classified as critical, was found in cyberhobo Geo Mashup Plugin up to 1.13.18 on WordPress. This affects the function esc_sql of the component Geo Search Feature. The manipulation of the argument map_post_type with an unknown input leads to a sql injection vulnerability. CWE is classifying the issue as CWE-89. The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The Geo Mashup plugin for WordPress is vulnerable to Time-Based SQL Injection via the 'map_post_type' parameter in all versions up to, and including, 1.13.18. This is due to the `SearchResults` hook explicitly calling `stripslashes_deep($_POST)` which removes WordPress magic quotes protection, followed by the unsanitized `map_post_type` value being concatenated into an `IN(...)` clause without `esc_sql()` or `$wpdb->prepare()`. The 'any' branch of the same code correctly applies `array_map('esc_sql', ...)`, but the else branch does not. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database via a time-based blind approach. Exploitation requires the Geo Search feature to be enabled in plugin settings.

The weakness was shared by Naoya Takahashi. The advisory is shared at wordfence.com. This vulnerability is uniquely identified as CVE-2026-4061 since 03/12/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 05/03/2026). MITRE ATT&CK project uses the attack technique T1505 for this issue.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
